Hello All,<br> <br> I got a Encrypted (XOR) Loopback EXT2 Filesystem image, as part of Monta Vista Previewkit 3.1<br> <br> I was tring to install MVL3.1 Preview Kit on Fedora Core 4 (2.6.11-1.1369_FC4), as part of it, "install_previewkit" script needs to mount above Filesystem.<br> <br> Suggested change was to alter encryption=XOR to encryption=1.<br> <br> But no success, and I always gets error like this...<br> ===================================<br> mount: wrong fs type, bad option, bad superblock on /dev/loop1,<br> missing codepage or other error<br> In some cases useful info is found in syslog - try<br> dmesg | tail or so<br> <br> dmesg shows:<br> VFS: Can't find an ext2 filesystem on dev loop1<br> ===================================<br> <br> From Script I found, mount was returning err code 32.<br> <br> I also found that !
irrespect
of PASSPHRASE, error is same.<br> Whereas using same PASSPHRASE on redhat90, i get it easily mounted.<br> <br> Manually verbose mount shows:<br> =======================<br> mount: going to use the loop device /dev/loop1<br> Password: <br> set_loop(/dev/loop1,install-components/previewkit/RPMS.image,0): success<br> mount: setup loop device successfully<br> del_loop(/dev/loop1): success<br> mount: wrong fs type, bad option, bad superblock on /dev/loop1,<br> missing codepage or other error<br> In some cases useful info is found in syslog - try<br> dmesg | tail or so<br> <br> <br> Strace Showed:<br> ============<br> mount("/dev/loop1", "RPMS", "ext2", MS_POSIXACL|MS_ACTIVE|MS_NOUSER|0xec0000, 0x925a000) = -1 EINVAL (Invalid argument)<br> <br> I doubt in FC4, passphrase is "\n" sensitive. If yes how to avoid it.<br> I wonder, if this is true, then how come set_l!
oop is
success.<br> <br> regards,<br> - nalin<br> <p>
